Description

Jointcal currently defaults to using LoadAstrometryNetObjectsTask for its refObjLoader. This can be dangerous in that if one doesn't retarget in the config, loading the skyCircle will fail and getting to that point can take a long time with lots of files.

We also plan to phase out A.Net catalogs over time, so this is a good idea long term as well. It does require some reconfiguration of the unittests however.
